New Law Tenements Built on or after 4/12/1901 but before 1916 are:
Generally____ or _____ stories high
____‘to____’ wide
____’ in depth
six or seven stories
35’ to 50’ wide
85’ in depth
NLT(4/12/1901-1915) access to the cellar will be ________.
an exterior stair
New Law Tenements built from 1916-1929 have a much larger floor area than previously built NLTs. To avoid having to be fireproof construction the floor areas were broken up into _____ square feet or less.
2500
In newer NLTs(1916-29) between some apartments there are brick or fireproof partitions which effectively limit the horizontal spread of fire. However, these dividing walls only go as high as the ceiling of the top floor. This results in a very large undivided cockloft area. Fire can, and often does, spread throughout this large cockloft area.
T/F
true
In newer NLTs the Entrance to the basement is by a side or rear door at that level, accessed via an exterior stair from the first floor, or through a passageway located in the front of the building.
true
in nonfireoroof construction firewalls extend to:
before 1930
1930-1940
after 1940
before 1930 as high as the ceiling on the top floor
1930-40 underside of the roof boards
after 1940 to the top of the roof boards

In OLTs and NLTs roof hoseline should be used only to: (choose the incorrect choice)
A. prevent fire from extending past the trench
B. to protect exposures
C. to extinguish fire that cannot be reached from below, such as fire in a cornice
D. operate briefly into ventilation holes to protect members operating on the roof
D.
Hoselines should not be operated into ventilation holes from the roof as this decreases ventilation and nullifies the action of lines operating on the top floor
At a MD fire the first line can be advanced when (choose the correct answer)
A. Ladder Co confirms the fire apt
B. the IC gives permission
C. the safety of the stairway is assured
D. once the line is charged and bled
C
The first line stretched for a fire in a multiple dwelling should be stretched by way of the interior stairs. The primary purpose of this line is to safeguard the stairway so that it can be used by the escaping occupants
Which is not a correct use of the 3rd line at a MD fire?
A. up the interior stairs
B. rope stretch into a window
C. up a fire escape
D. into an exposure as ordered by the IC
A
This is especially true in Old Law Tenements because the stairway is narrow and the stretching of a third line via the interior stairs would result in congestion and inability to move any of the hoselines.
Windows should be opened ___ from the top and ____from the bottom to allow heat and smoke to vent and cool air to enter the room
2/3s from top
1/3 from bottom

A. ladder officer in the fire area
B. the IC
C. engine and ladder officer in the fire area
D. engine officer in fire area
B. IC
At a cellar fire in an old law tenement, which is the assignment of the 1st line and which is the assignment of the second?(A or B)
A. should be advanced into the cellar by way of the front or rear entrance to the cellar.
B. stretched to the cellar entrance door which is located inside the building, under the interior stairway on the first floor
A. 2nd line
B. 1st Line:
This line should not be advanced down the cellar stairs if there is an outside entrance to the cellar at the front or rear of the building, unless the fire is minor.
Cellar fires in OLTs generally do not spread to upper floors quickly because of the fireproof ceiling.
T/F
False
Fire may spread quickly. Cellar ceiling is not fireproof
At a store fire in an OLT the second line should be stretched to:
A. the store as BU for the 1st
B. the entrance hallway
C. apt above the store
D. outside the main entrance of the building
B
When assured that the second line is not needed on the first floor, it may be advanced to the floor above the fire.
In OLT shaft fires, a hoseline should be stretched to the nearest point from which water can be directed onto fire in the shaft. Sufficient hose must be stretched to reach the upper floors of the building.
T/F
true
For fires in rooms in the vicinity of a shaft, once the fire has been knocked down continue through the apartment and complete final extinguishment of the interior before operating into the shaft.
T/F
false
after the fire in the room has been knocked down, the line should be operated into the shaft in order to knock down the shaft fire before continuing through the apartment for knockdown and final extinguishment.
An OLT converted to an SRO is required to have sprinklers in each room and the hallway. Can we supply these systems?
no
The sprinkler system has no roof tank; it is supplied from the water main in the street.
In H type buildings which type of stairs are a tremendous asset in heavy fire operations on the top floor?
A. transverse
B. wing
C. isolated
A
a person can go (transverse) from one stairway to another via the public hall on all floors
In H type buildings stairs with floor landings with limited limited space and absence of a public hall are:
A. transverse
B. wing
C. isolated
C
usually identified by their individual entrances
Access is limited to the apartments served by the stairs, and there is no access to other wings and hoseline operations are confined to their limited area.
Located at the front and rear of each wing. The floor landing leads to the public hall that will join the other stairs in that wing only (if two stairs). These stairs are:
A. transverse
B. wing
C. isolated
B
The public hall does not transverse to the other wing of the H .
If the fire is showing out windows in the throat, courtyard and front windows, and a tower ladder stream is being used, it should be directed at the windows in the ________ first.
throat
The stream should then be advanced toward the front of the building and finally operated into the front windows
In an H type, the primary means of getting to the roof would be a transverse stairway in the same building or any stairway in an adjoining building
T/F
false
winged or isolated stairways or any stairway in an adjoining builsing
